Used primarily in organic synthesis as a versatile intermediate for constructing more complex molecules. It plays a key role in the development of pharmaceuticals, particularly in the synthesis of heterocyclic compounds with potential biological activity. Its iodine moiety makes it valuable in cross-coupling reactions, such as Suzuki or Sonogashira couplings, which are essential in drug discovery and material science. Additionally, it is utilized in the preparation of agrochemicals and functional materials due to its reactive nitrile group, which can be further modified to introduce various functional groups.
